DescriptionThe air conditioning system includes the heater and has the functionof producing cold, dehumidified air by switching on the compressorand the refrigeration system.The climate control system is operatedthrough two control knobs in the dashboard (each knob carries outa dual function: one with an outer ring nut, one with a proper knobin the centre:the ring nut for the left knob mechanically controls themixture flap between hot and cold air; the inner knob electricallycontrols the ventilation of the air at four different speeds;the ring nut for the right knob, mechanically operatedvia a cable, controls the opening of the flaps which regulate thedistribution of air flows; the inner knob mechanically controlsthe engagement of the recirculation function. The control panel also contains the buttonfor engaging the air conditioning compressor 2428101SeeE6021COMPRESSOR ENGAGEMENT . For more details, 2427438Characteristic of working principle5040AIR CONDITIONING CASINGAND COMPONENTS There is also a red button in the controlunit for switching on the hazard warning lights 2427911SeeE2020DIRECTION INDICATORS / HAZARD WARNING LIGHTS anda button for switching on the heated rear windscreen 2427965SeeE3030HEATED REAR WINDSCREEN AND DOOR MIRROR DEFROSTING . The fan is supplied by a line protectedby a special fuse and controlled by a special relay in the enginecompartment control unit.The operation of the fan at different speedsis achieved through a resistive divider, protected by a specialthermal fuse to prevent overheating.The control unit is supplied by a line controlledby the ignition and protected by a fuse in the underdashboard controlunit.
Functional description Fan N85 is supplied when the ignition is switched on (INT/A)from the line protected by fuse F31 of the junction unit B2 underthe facia and controlled by the relay T8 dedicated fuse F8 of theengine compartment junction unit B1. Control knob H81 controls the fan atdifferent speeds via regulator O30: the control signal - earth signal- varies according to knob position and crosses or does not crossthe coils of regulator O30 to determine four different voltage signalsfor fan N85, which thus turns at 4 different speeds.767 The fan N85 operates at thefirst speed if the button for engaging the compressor is pressed,even if the control knob H81 is in position '0' SeeE6021 COMPRESSOR ENGAGEMENT .
